i rlly cant spend 4$ every day on lunch
Make your own lunch.
A loaf of bread costs £1, and gives 20 slices. That's 10 sandwiches, or 20 halves.
A pack of 30 wafer thin ham slices is £1.50. Given two slices per sandwich, that's 15 sandwiches.
A tub of butter is £1-2, and will last months.
For £2.50 you can make 10 sandwiches, enough for 10 days. That's 25p a day.
A can of Monster is £1.35. That's £13.50 for 10 days.
Of course, bread goes stale within 10 days, so it might last only 4-5 days.
That could mean just 4-5 sandwiches, but that's still 62p a day. Less than half the price of an energy drink.
